Answer this question truthfully
### Question: What causes enterobiasis?
### Response: Enterobiasis is caused by pinworms. Pinworms are the most common worm infection in the United States. They are most common in school-age children. Pinworm eggs are spread directly from person to person. They can also be spread by contamination of household items with the eggs. Typically, children are infected by unknowingly touching pinworm eggs and putting their fingers in their mouths. The eggs are swallowed and eventually, matures in the small intestine. Female worms then move to the child's anal area and lay eggs, usually at night. This may cause intense itching. The area can also be infected. When the child scratches the itching anal area, the eggs can get under the fingernails. These eggs can be transferred to other children, family members, and items in the house.
